The Drower Collection (DC), held at the
Bodleian Library in
Oxford University, is the most extensive collection of Mandaean manuscripts. The collection consists of 55 manuscripts, many of which Drower had obtained through the Mandaean priest Sheikh
Negm bar Zahroon. Drower donated MSS. Drower 1-53 to the
Bodleian Library in 1958. MS. Drower 54,
The Coronation of the Great Šišlam, was given to the library by Lady Drower in 1961. MS. Drower 55, Lady Drower's personal notebook, was added in 1986. After her death, some of Drower's private notebooks were obtained by
Rudolf Macúch. These notebooks are not part of the Bodleian Library's Drower Collection. MS. DC 2, which was copied by
Sheikh Negm for Drower in 1933, mentions the
Mandaean baptismal name (i.e., spiritual name given by a Mandaean priest, as opposed to a birth name) of E. S. Drower as
Klila pt Šušian (), as her middle name Stefana means 'wreath' in Greek. MS. DC 26, a manuscript copied by copied by Sheikh Faraj for Drower in 1936, contains two
qmahas (exorcisms). MS. DC 26 is dedicated to Drower's daughter,
Margaret ("Peggy"), who is given the Mandaean baptismal name
Marganita pt Klila () in the text. ==Letters==
